Share your CCDA v2.1 Experience

@Rodrigo: your link doesn’t work for me i don’t know why, in addition if we calculate we will have like this:

G.711=64Kbps
Packet Header : 6 bytes
Payload: 160 bytes

which means 64.000+166+6 = 64166

Our bandwidth is 768Kbps Then 768/64.166 = 11.96 => that’s almost 12

so what you think

can anyone help me with this question, it sounds strange as the answer provided is C

Your company uses OSPF for internal routing. The company will be connected to VendorA via a single dedicated link and to VendorB via redudant dedicated links. Both vendors also use OSPF for internal routing. Which of the following deployements describes the best intra-domain routing practice in this situation?

A. Redistribute the routes on each link between your company and the vendors to a shared EIGRP routing protocol.
B. Use IBGP to reach VendorA and EBGP to reach VendorB
C. Use static routes to reach VendorA and EBGP to reach VendorB
D. Use Static routes to reach both VendorA and VendorB
E. Connect your company to both VendorA and VendorB using existing OSPF.

I thought it was 11 calls too. But after reading again, the payload for G.711 is 80K. If you used 64K in your calculation, you would get 11 calls, which is wrong, and thats what I did. 64K is the G711 bandwidth on a voice T-1, its 80K when converted to VoIP.

@Rodrigo i think you are right, i checked here:

http://www.voip-calculator.com/calculator/lipb/

and i got 9 calls

you are right also @Tony

check here : http://www.voip-sip.org/voip-codec-payload-bandwidth-required/

@Tony : please post me the calculation formula to calculate it

I didn’t go through the whole calculation. I just did 768/80 which equals 9.6 calls.

Passed exam 927. Used. Fred’s and p4s dumps although p4s is more accurate. 4 new questions and 3 new DnD.

Did Cisco just raise the price of this stupid test to $200? A-holes!

confirmed……F*cking Cisco:

“…The price changes are effective Monday, January 16, 2012.

CCNA exam 640-802 is increasing from $250 to $295
CCDA exam 640-864 is increasing from $150 to $200
ICND1 640-822 and ICND2 640-816 are increasing from $125 to $150”

“…The price changes are effective Monday, January 16, 2012.

CCNA exam 640-802 is increasing from $250 to $295
CCDA exam 640-864 is increasing from $150 to $200
ICND1 640-822 and ICND2 640-816 are increasing from $125 to $150”

@ccda20 : what are the new questions please

Guys look at this D&D

MIB – selection not used
SNMP – manages with UDP
RMON – uses agent for long term analysis
CiscoWorks – management tool

Isn’t RMON uses probe as agent???

hey guys what resources did you use for ccda?

i have the official ccda 640-864 book….what else do you think i need?

hi ccda20, what questions u faced in the exam that are not inside p4s or fred dump? i taking my exam in a couple of hours time.

Another wrong answer…The wireless controllers should be connected to the core layer and not to the distribution.

this bitch of an exam costs $200 now?

@testtaker : please let us know what question they gave you including the new DnD ok friend? thx bro

30 minutes and I will start the exam

Passed! Some new qns as mentioned here.i not sure of the answers just gues and think if they make sense to be right.good luck pple! :)

passed 956/1000

about 3 new D&D and 3 new questions I will try to remember:
1- What are the recommended step in characterising existing network:
– Obtain exisitng documentation, use organizational input, analyse the network, and something else..
The other options are starting from analysing network and testing network which is incorrect

2- When designing the datacenter 3.0 which is not a relevant solution in datacenter virtualization:
– an application virtualized in a desktop computer, transfered to server to be virtualized
– A media access service virtualized across fiber infrstructure (I chose this)
– Something about vsan and vlan virtualizatio

D& D = HTTP/EMAIL/ IP Phone / Voice / BUDGET/SECURITY /APPLICATION.
http/email——————application
ippohne/voice————– network services
Budget———————Business constraints
security——————–Technical goals

D&D=Data Center Virtualization/ VSAN/ Cisco Unified Communication System
Cisco Unified Communication System—————-Cisco nexus1000 and enforcing vm security
Vsan/vlan————————network and server virtualization
don’t remember the others

D&D
snmp————— defines the communication type or something like this
cdp—————–uses layer 2 and muticast
netflow————-
rmon—————————Acl and security analysis

I got all the other questions from pass4sure collection, and I got those questions which are wrong by p4s and chose the answers I assume is correct.
I got also this question:
Your company uses OSPF for internal routing. The company will be connected to VendorA via a single dedicated link and to VendorB via redudant dedicated links. Both vendors also use OSPF for internal routing. Which of the following deployements describes the best intra-domain routing practice in this situation?

D. Use Static routes to reach both VendorA and VendorB
E. Connect your company to both VendorA and VendorB using existing OSPF.
I chose C

Also this:
The entreprise campus core layer has requirements that are unique from the distribution and access layers, which of the following is true about the core layer?

A. The core provides convergence using layer 2 and layer 3 services and features.
B. The core provides high availability to support the distribution layer connections to the enterprise edge.
C. The campus core layer is optional.
D. The core layer requires high performance to manage the traffic policing across the backbone.

I chose C

@pass4sure & @testtaker : congratulations, don’t stop go ahead for CCDP

@pass4sure: thank you alot for remembering me and come back to tel me the new questions, if you need any help just email me l1rz1m@gmail.com

Thanks my friend, you are the man……

Thanks all for your support, if you need any question tell me, I will stay here for some time

There are a number of advantages to using virtualization within the data center module. Which the following two are samples of these advantages?

A. Virtualization consolidates many low-performance devices into a few high-performance devices, providing a more efficient utilization of hardware and increasing the price/performance ratio.

B. Virtualization compartmentalizes a single device into a few high-performance devices, providing a more efficient utilization of hardware and increasing the price/performance ratio.

C. Dynamic forcibility eliminates the need add, reassign, or repurpose resources in the system.

D. Virtualization separates user via different physical networks into groups with visibility into only their logical network.

E. Virtulization provides distinct security polices per physical device.

thank you pass4sure for your assistance

What are the two most likely driving forces motivating businesses to integrate voice and data into converged networks? (Choose two)

A. Voice has become the primary traffic on networks.
B. WAN costs can be reduced by migrating to converged networks.
C. Their PSTNs cannot deploy features quickly enough.
D. Data, voice, and video cannot converge on their current PSTN structures.
E. Voice networks cannot carry data unless the PRI circuits aggregate the BRI circuits.

there are 3 correct answers, B,C,D(acording Reference guide)… I think E is not an option, if i am wrong please correct me….

B & D

Yes B & D

A. Virtualization consolidates many low-performance devices into a few high-performance devices, providing a more efficient utilization of hardware and increasing the price/performance ratio.

B. Virtualization compartmentalizes a single device into a few high-performance devices, providing a more efficient utilization of hardware and increasing the price/performance ratio.

C. Dynamic forcibility eliminates the need add, reassign, or repurpose resources in the system.

D. Virtualization separates user via different physical networks into groups with visibility into only their logical network.

E. Virtulization provides distinct security polices per physical device.

A,B answers D and E looks correct but there are playing on the words,
because Answer D “Virtualization separates user via different physical networks into groups with visibility into only their logical network”. on the book they say separation of user group on the same physical network.

and answer E on the book they say provide per department security not per physical device

hmmmm so A&B ok. they gave that question?

and i think it makes sense, because you can gather low performance staff to make it 1 solid powerfull thing, and also you can devide a powerfull machine to many single devices as of course virtualization & vmware

of course, Yes I got this question

I remember most of the questions I got

all my concern is with the D&D how many D&D they gave you???

about 9 or 10

wooooooooooow :D you must be stressed during the drag&drop :P

confrat Pass4sure..:).. you’re a great man

but would you explan this please.. i didn’t get it! where is the question & where is the answer?

D&D=Data Center Virtualization/ VSAN/ Cisco Unified Communication System
Cisco Unified Communication System—————-Cisco nexus1000 and enforcing vm security
Vsan/vlan————————network and server virtualization

I think this one is new……can someone verify the answer?

B. The core layer provides high availability to support the distribution layer connections to the
enterprise edge.
C. The campus core layer is optional.
D. The core layer requires high performance to manage the traffic policing across the backbone.
Answer: C

and this one:

Refer to the exhibit.
***Exhibit Missing***
Which statement is true concerning enterprise edge distribution switches?
A. The speed of switching is the most critical feature.
B. Security requirements are offloaded to the other modules for performance reasons.
C. Edge distribution switches are only required when using a collapsed core backbone.
D. Enterprise edge distribution switches are similar to the building distribution layer.

Answer: D

and yet another new one:

Which one of these statements is true concerning the data center distribution (aggregation) layer
design?
A. With Layer 3 at the aggregation layer, the physical loops in the topology must still be managed
by STP.
B. The boundary between Layer 2 and Layer 3 must reside in the multilayer switches, independent
of any other devices such as firewalls or content switching devices.
C. A mix of both Layer 2 and Layer 3 access is sometimes the most optimal.
D. In a small data center, the aggregation layer can connect directly to the campus core,
exchanging IP routes and MAC address tables.
Answer: C

pass4sure.. i did the exam & failed ..but i remember there was a question have 8 multiple choice

i think this one

Topology for the Cisco enterprise architecture.
and the question was something like, in which portion of the network you will use Public IP addressing? “Choose three , out of 8 options , you will definitely narrow down your options to the enterprise edge module ”

1- VPN / Remote access.
2- Internet Connectivity.
3- WAN / MAN.
4- E-commerce.
5- …………
6- ………..
7- ………
8-………….
the trick is which portion you will not choose out of the above mentioned 4 enterprise edge options

so would you clarify that please

Jesus, they really had a bunch wrong! No wonder a bunch of people failed in the past month. Old study material listed the answer as A but it’s corrected below:

QUESTION NO: 45
When designing the wireless portion of an enterprise campus network, which one of these
statements should serve as a strict guideline?
A. Wireless controllers should be distributed throughout the building distribution layers
B. Dynamic controller redundancy, where the access points attempt to join the least loaded
controller, is a best-practice approach.
C. Wireless controllers should be centralized in the core layer
D. To improve the RF coverage, the controllers of any building should be put in the same mobility
group.
Answer: C
Explanation:

ANother one that looks like it changed…..on actualtests :

QUESTION NO: 7
Which one of these statements should the designer keep in mind when considering the advanced
routing features?
A. one-way router redistribution avoids the requirement for state or default routes.
B. Redistribution, summarization, and filtering are most often applied between the campus core
and enterprise edge.
C. Filtering only occurs on the routing domain boundary using redistribution.
D. Summarize routes at the core toward the distribution layer.
E. The hierarchical flexibility of IPv6 addressing avoids the requirement for routing traffic reduction
using aggregation.
Answer: B

A couple days ago their material said the answer was E! I’ve answered E the last time i took the test and failed! Can someone verify if these updated answers from actualtests are correct?

QUESTION NO: 16
In terms of remote office design, which one of these statements is a characteristics only of a small
remote office (up to 50 user), and not of medium or remote offices?
A. Link redundancy to access layer switches is not possible with an integrated design.
B. A collapsed access and distribution layer is required.
C. There are no loops in the network design.
D. Layer 3 services such as DHCP, firewall, and NAT are provided by enterprise campus.

Answer: C actualtests old answer was B anyone?

QUESTION NO: 7
correct answer is E….Redist,summary…etc applied to distribution layer towards to core..
QUESTION NO: 45
correct answer is C…Not only in reference guide even cisco sites about design practices. it should be centralize at core.. it can be done as distributed but cisco recommends core centralize…
